CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 233,717, dated October 26, 1880.

Application filed May 8, 1880.

To all whom zt may concern:

Be it known that I, JOHN VINCENT, of Decatur, in the county of Macon and State of Illinois, have invented a new and useful Improvement in Check Row Attachments for Corn-Planters, which improvement is fully set forth in the following specification.

My invention relates to check row cornplanters; and the improvement consists of a series of grooved pulleys and a cord passing thereon, arranged so that the cord will not slip on the pulleys, thereby operating the shaft so that the corn shall be dropped at regular distances apart, thus doing away with the necessity of using a knotted cord or a cord with buttons thereon. At each end of the field, an adjustable cord-stop is attached for the purpose of starting and stopping the motion of the shaft, which is attached to the slide-valves of the corn-reservoir. I attain this object by the mechanism illustrated in the accompanying arranged on the pulleys. Fig. 2 is aplan of. the same. Fig. 3- is an enlarged longitudinal view of the cord-stop. Fig. 4 is an end view of the same. Fig. 5 is a view of the cord-stop in detail. Fig. 6 is a plan of the triangular cam and (loublepronged check-lever. Fig. 7 is an elevation of the same. Fig. 8 is a sectional view of the grooved driving-pulley, taken on the line w m, Fig. 2, showing the spurs on the side of the groove.

To enable others to make and use my improved attachment, I will describe its parts and their operation.

A is the frame, to which all the parts are directly or indirectly attached. B is the cord, which is fastened at each end of the field, as in all other planters.

G is the grooved driving-pulley, said groove being made V- shaped and provided with a series of spurs, a, on each side of the groove, to prevent the cord from slipping. Said pulley is further provided with a large hub, 0,

spaces, for the purpose of transmitting motion to the shaft (on which it is intended to run loosely) by means of a clutch-box, J, coacting projections, and interdental spaces.

The cord B passes on the pulley D and un- 1 (Model.)

der the idler.,E, thence over the grooved driving-pulley G, thence under the idler Gr, thence between the prongs of the check lever B, thence on the pulley I, thence to the other end of the field, the cord being so arranged as to insure the rotation of the grooved drivingpulley 0 when the machine is drawn.

I attach to the cord an adjustable cord-stop, L, at each end of the field, a suitable distance from the stakes, to which the ends of the cord are fastened, to allow the turning of the machine between the cord-stops and the stakes, so that when the machine is drawn across the field alternately the cord-stop L, in passing around and over the several pulleys comes in contact with the three-armed check-lever H H H, thus causing it and the triangular cams K, to which said check-lever is attached, to make onethird ofa revolution,thereby disconnecting the clutch and stopping the rotation of the shaft through the medium of the forked lever M, pivoted at d. The cord-stop is especially constructed to operate in conjunction with the check-lever, and consists of a body, b, and cylinder 0, each having a slot longitudinally, for the purpose of inserting the cord. The body I) is also provided with a pin,f, that pierces the cord and prevents it from slipping. A portion of the body is made small and a thread cut thereon for the purpose of screwing on the cylinder 6. Said cylinder is also slotted, and when screwed tight up to the shoulder on the I body I), said slot must be on the opposite side reverse to the slot in the body. By this means it will be seen that it is impossible to remove it from the cord. When it is required to be removed from, changed, or adjusted on the cord, this may be done by turning the cylinder one-half round to bring the slots both in a line, then remove the cord from the slot. Both ends of said cord-stop are the same form, so that when the machine is drawn past the cord-stops and is between it and the stakes, having operated the check-lever and disconnected the clutch, thereby stopping the corn from dropping. It is returned in the same way, and its passage back around and over the pulleys comes again in contact with the checklever from an opposite direction from that in which it first passed through, carrying the check-lever back to its former position, throwing in the clutch and operating the seed-slide at precisely the same point at which its operation was arrested, thus making all the rows of even length, which is the principal object of my invention.

N is a guide to prevent the cord-stop from passing the arms of the check-lever without acting thereon.

The frame A is attached to the corn-planter by any suitable connection, and a crank or other suitable connection made between the shaft 0 and the seedslides, so as to give the seed-slide a reciprocating motion, the shaft and driving-pulley moving in reverse direction as the planter is turned at each end of the field.

I am aware that previous to my invention check-row planters have been made to use a cord without a cord-stop or button thereon. ThereforeI do not claim such a device, broadly; but

What I do claim, and desire to secure by Letters Patent, is-

1. In acheck-row corn-planter, the combination of the grooved drivingpulley G with the spurs a, hub c, clutch-box J, forked lever M, cam K, check-lever H H H and guide N, all substantially as shown and described.

2. In a check-row corn-planter, the combination of the driving-pulley (J, hub a, clutchbox J, and forked lever M, substantially as shown and described.

3. In a check-row corn-planter, the checklever H H H and cam K, in combination with the forked lever M, substantially as shown and described.

4:. An adjustable stop for a check-row cord, made in two sections and screwed together, forming one body, and consisting of a body, 1), cylinder e, and pin f, substantially as shown and described.
